I too hate testing water, and I almost never do it.
I also occasionally buy fish that I have no room for, resulting in overstocking. I have two Rainbow Cichlids in a 30 gallon tank with 3 Orange Chromides, 2 Indian Glassfish (no, not the dyed type), 3 mollies and a bristlenose pleco.
In related news - does anyone know where I can get real non-dyed Indian Glassfish in NYC/LI and does anyone want some Rainbow cihclids?
Have you succumbed to the pleasure of Multiple Tank Syndrome? I feel your pain!
